BRUSH FOR BOTTLE-WASHING MACHINES.

Application filed November 20, 1913.

'To all whom t may concern:

Be it known that I, JOHN M. JUNG, a citin zen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and use= ful Improvements in Brushes for Bottle-Vashing Machines, of which the following is a description.

My invention relates to an improved brush and spindle therefor forwashing bottles. In machines of this type, ordinarily from one to twentyor more spindles and brushes are employed upon each washing machine, sothat a number of bottles may be Washed at the same time. For economy ofspace the brushes and spindles are ordinarily set quite close together,so that the brushes should be attached to the spindles in such a Waythat they may be easily reached and quickly removed, and in a multiplespindle machine it is desirable that they be removed with as little lossof time as possible. Owing to the wear on the brushes, it is alsonecessary to frequently renew them.

The present invention resides particularly in an improved spindle andbrush therefor, which brush may be easily attached or detached in aninstant without requiring any special tools for the purpose.

The invention has among its further objects the production of a deviceof the kind described that is simple, convenient, durable, efficient,and satisfactory, that is economical in price, as well as economical inuse.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out in the claim.

In the drawings, wherein like reference characters indicate like orcorresponding parts, Figure 1 isa side elevation of a portion Of aspindle and brush carried thereby; Fig. 2 is substantially a sectionalview on line 2, 2 of Fig. l; Fig. 3 is a perspective view of the lowerend of the spindle; Fig. 4 is 'a perspective view of a cooperating brushpart; Fig. 5 is a perspective view of a portion of the end of the brush.

Referring to the drawings, and particularly Figs. 1 to 5, 1 represents asuitable brush, or rather the bristles part of the brush, which aresecured to a shank 2, ar-

serial no. soaosaj ranged to be carried by aspindle 8 ofthe washingmachine. It may be mentioned that while in the drawings the spindles areshown with the brushes apparently on the lower ends thereof, inoperation it is iinmaterial whether the brush is at the upper end of aspindle, which spindle is supported v from below, or at the lower end ofa spindle carried from its upper end. Usually, however, the spindle issuitably carried by the washing machine at its lower' end, and thebrushes arranged upon theupper ends of the various spindles, oroppositeto the ar'- rangement shown in the drawings. In the brushconstruction shown, the shank 2 is of twisted wire and formed with theends 4, 4

preferably extending 4transversely to the shank, so as to detachablyengage the spindle. As shown, the spindle is preferably tubular andslotted lengthwise as 'at 5, 5, and transversely as at 6, and preferablynotched as at 7. The slots 5, 5 are of a size to admit the ends 4, 4 ofthe shank 2, the brush being positioned by a longitudinal or lengthwisemovement of the shank, and then turned so as to engage the ends `4, 4 inthe notches 7, 7 The brush is maintained in position by a spring 8, orits equivalent, which preferably bears against In order to center theshank of the brush in the spindle, I preferably provide a member l0,which may be flanged at 1l, and is slotted as at 12, the same having anopening 13 of suitable size, so that the member normally closely fitsthe shank of the brush. This member may be positioned on the brush withthe ends'4, 4 projecting through the slots 12, 12, and the brush andmember then positioned or inserted in the spindle. When so positionedthe spring 8 bears upon the end of member l0, and firmly maintains thebrush in position in the spindle. The spindle may be connected to thewashing machine in any desired manner. Asshown, it is slotted as at 14,and formed as at 15, arranged to engage a suitable cooperating rotatingpart of the machine. The machine itself may be of any desired type andcontain any desired number of spindles. With the device constructedsubstantially as shown, any brush may be inserted or removed in aninstant without requiring any special tools. There is nothing to stickor bind as in a screw threaded construction for example. It will also benoted that the brush part, consisting of the bristles l and shank 2,when worn out, may be easily renewed or replaced, and with a minimum ofcost, since only the worn-out parts are required t-o be replaced.

It will be noted that with the constructions shown, the brush may besnapped on or olf in an instants time. The matter of time saving inremoving or replacing brushes is of no small importance when it isconsidered that a machine may have from 16 to 20 spindles, or more,usually arranged very close together, so that it is ordinarily difiicultto reach any with a wrench, screw driver or the like, to release theparts, particularly where the brushes are attached directly to thespindle by athreaded or similar engagement. Likewise with a threadedengagement of the brush and spindle it may oftentimes stick and bind,and it would be no uncommon occurrence to require ten to twenty minutestime to remove one brush. With my constructions all may be removed orreplaced in a very short time. lVith the present construction, shouldthe machine be accidentally reversed, as is sometimes the case, therewould be no unscrewing or dropping out of the brushes. Of course wherethe brushes are at the top of the spindle there is no tendency for thebrush to drop out. Another important feature is the economy inmanufacture and use. With the device not only is time saved, but thebrushes need not have a tip permanently secured thereto, and may bepurchased without tips at a considerably lower price, and operate inexactly the same manner. This cost is not a small item when it is to beconsidered that with hard usage, for instance in a brewery, the life ofa brush may be limited to a days use or less, and there may be in usefrom one to half a dozen or more machines, each provided with aplurality of spindles.

VHaving thus described my invention, it is obvious that variousimmaterial modifications may be made in the same without departing fromthe spirit'of my invention; hence I do not wish to be understood aslimiting myself to the exact form, construction, arrangement orcombination of parts herein shown and described, or uses men- What Iclaim as new and desire to secure by Letters Patent is A device of thekind described, comprising a tubular spindle, slotted lengthwise at oneend for a portion of its length, and slotted circumferentially at theinner end of said lengthwise slots, and slightly slotted at the closedend of said second mentioned slots toward the said end of the spindle, abrush provided with a twisted wire shank formed with the ends of thewires projecting on opposite sides thereof, and of a length to engagethe spindle in said last mentioned slots from the interior of thespindle, a bushing detachably arranged on said shank, comprising atubular member' JOHN M.
